With a dust and moisture resistant design, the compact and lightweight Sony Vario-Tessar T* FE 16-35mm f/4 ZA OSS Lens covers your wide-angle zoom needs and is designed for full-frame E-mount cameras but can also be used on APS-C E-mount cameras as well. A constant f/4 maximum aperture offers consistent performance throughout the zoom range. Benefiting working in dim light is Optical SteadyShot image stabilization, which serves to minimize the appearance of camera shake by up to four shutter speed steps.
